A CSR Rankings Riddle

It was brought to my attention that I have not yet done a comparison of RiskMetrics Group's Global ESG 100 with the four other CSR rankings I have cross-referenced in previous posts.* So here goes: the first of two posts. Today I will leave you with a riddle about the one thing that the CRO, Ethisphere Institute, Newsweek, Corporate Knights, and RiskMetrics Group universally agree upon. Next week, I will reveal the answer, and will present my full analysis of overlap between the latest Global 100 ranking and the four other previous CSR rankings I have covered in this series.

First, a bit about the two versions of the Global 100. Up until last year, there was one Global 100 published by Corporate Knights but developed by RiskMetrics Group. This year, RiskMetrics Group and Corporate Knights parted ways. From what I understand, Corporate Knights decided to apply a new approach, while RiskMetrics Group decided to continue applying its time-tested methodology.

So, now my riddle: in comparing the RiskMetrics Group Global ESG 100 to the top 100 lists developed by CRO, Ethisphere Institute, Newsweek, and Corporate Knights, a single company made all five lists. Can you guess what it is?
